The only thing I would change is wrap your secondary spring at 3-2, 50 degrees.Hey there I have a 2017 BTX , 270 race hurricane tune , Dalton adjustable weights, Thunder products Orange Springs, and glide washers, 911 cover, also thunder products hole shot 33/35 helix . Seems to work pretty good never got a Lot of use yet but most on here are saying that helix and spring are no good for The race tunes? but most seem to be driving regular studded length tracks so I'm wondering if I should change anything belt temperatures seem good
